Speedodometer stopped working, o/d light flashing and my truck does not want to go out of first gear???
The best thing would be to have transmission control module - ( computer ) checked for DTC'S - diagnostic trouble codes . The flashing O/D light is trying to tell you that . The transmission is in limp home mode . A sensor or shift solenoid is most likely the problem . Your transmission is electronically controlled , has sensors , shift solenoids , an a computer that controls it all , plus electrical signals (inputs) from the engine computer .
